Title: Bumped semiconductor device and method for bumping a semiconductor device
Inventor: YANG HONG-ZEN
IPC: H01L23/488
Filed: 2003-05-21
Abstract: A method for bumping a semiconductor device with at least one contact pad is disclosed. First, an under-bump metallurgy layer which has a copper layer is formed on the contact pad of the semiconductor device. Then, a solder bump is selectively formed on the under-bump metallurgy layer at a location corresponding to the contact pad of the semiconductor device, wherein the solder bump directly contacts the copper layer of the under-bump metallurgy layer. After the solder bump is reflowed to yield molten solder that wets and bonds to the contact pad of the semiconductor device, the semiconductor device is heated under a temperature between about 135 DEG C and about 175 DEG C for about 30 to about 40 minutes. The present invention further provides a semiconductor device provided with at least one solder bump made by the aforementioned method.

Title: Fabrication of a waveguide taper through ion implantation
Inventor: SALIB MICHAEL S
IPC: G02B6/122
Filed: 2003-05-30
Abstract: A method to form a taper in a semiconductor layer. In one embodiment, the semiconductor layer is formed on a cladding layer. A mask layer is formed on the semiconductor layer. The mask layer is patterned and etched to form at least an angled region and a thick region. An ion implantation process is performed so that the portion under the angled region is implanted to have an interface or surface that is angled relative to the surface of the cladding layer. This angled surface forms part of the vertical taper. The implanted region does not contact the cladding layer, leaving an unimplanted portion to serve as a waveguide. The portion under the thick region is not implanted, forming a coupling end of the taper.

Filed: 2003-07-02
Abstract: An electronic device (70) comprises a thin film transistor (TFT) (9,59), the TFT including a channel (16) defined in a layer of polycrystalline semiconductor material (10,48). The polycrystalline semiconductor material is produced by crystallising amorphous semiconductor material (2) using metal atoms (6) to promote the crystallisation process. The polycrystalline semiconductor material (10) includes an average concentration of metal atoms in the range 1.3 x 10<SP>18</SP> to 7.5 x 10<SP>18</SP> atoms/cm<SP>3</SP>. This enables polycrystalline semiconductor TFTs to be formed with leakage properties acceptable for use in active matrix displays using a metal induced crystallisation process of duration significantly less that previously thought necessary. Furthermore, this process duration reduction facilitates the reliable fabrication of poly-Si TFTs having bottom gates formed of metal.

Title: Microwave apparatus to accelerate CD recycling by pre-damaging
Inventor: WANG JENN-SHING
IPC: B09B3/00
Filed: 2003-07-29
Abstract: The present invention relates to a microwave apparatus to accelerate CD recycling by pre-damaging, and particularly to an apparatus for placing the optical recording medium under an electromagnetic wave environment so that energy of electromagnetic wave is concentrated to damage the film layer of the optical medium, including the protection layer in the optical recording medium, since this layer may hinder the subsequent recycling chemical reaction, so as to significantly increase the effective reacting interface of the chemical solution, and assist the chemical solution to further separate the film material from the substrate material along the cracks. The whole method is easy in operation, low in cost, and fast and reliable in dissolution, which is helpful in high-quality recycling the substrate and film material of the optical recording medium, and which can effectively avoid the secondary contamination in the recycling process.

Title: Net structure and method of making
Inventor: SETH JAYSHREE
IPC: A44B18/00
Filed: 2004-01-07
Abstract: The present invention concerns an extrusion formed reticulated web, mesh or netting including reticulated hook fasteners for use with hook and loop fasteners the polymer netting comprising two sets of strands at angles to each other. The first set of strands are a plurality of oriented (molecular orientation created by stretching) strands extending in a first direction and are generally mutually parallel and linear. The second set of strands are a plurality of substantially parallel strands attached only to a first face of the first set of oriented strands. The first set of oriented strands occupy a first planar cross-sectional area in the thickness direction of the formed netting. Said second set of oriented strands occupy a second planar cross-sectional area in the thickness direction of the formed netting. Preferably, these first and second planar cross-sectional areas are substantially mutually exclusive and are abutting. The polymer netting is preferably made by extruding a thermoplastic resin through a die plate, which die plate is shaped to form a base film layer and spaced ridges or ribs projecting from a surface of the base layer. The spaced ridges or ribs formed by the die form the first set of strands forming the reticulated mesh or netting. The second set of transverse strands are formed by transversely cutting the base layer at spaced locations along a length, at a transverse angle to the ridges or ribs, to form discrete cut portions. Subsequently longitudinal stretching of the ridges (in the direction of the ridges or the machine direction) separates these cut portions of the backing, which cut portion then form the second set of spaced apart strands of the reticulated mesh or netting.

Title: Printing method of shrinking inner electrode thickness of passive device
Inventor: WANG HUNG-GUANG
IPC: H05K3/14
Filed: 2004-03-19
Abstract: A kind of printing method for shrinking inner electrode thickness of passive device is disclosed in the present invention. In the invention, the originated spray-printing or roller printing inner electrode method is used to replace the conventional screen printing such that it is capable of manufacturing inner electrode having a sub-micrometer or nano-meter thickness. Thus, the laminating layer number of the corresponding inner electrode for the manufactured passive device can be greatly increased as compared with the conventional passive device having the same volume. As the inner electrode has a sub-micrometer or nano-meter thickness, the inner electrode is highly dense and the relative voltage tolerance is also greatly increased such that it is capable of forming a passive device having higher capacity. In addition, the conduction material thickness of the inner electrode for the manufactured passive device is decreased without affecting the operation characteristics of the passive device such that the manufacturing cost of passive device can be greatly decreased. For the practical application of the manufactured passive device, the entire total volume and height of the manufactured device can be greatly decreased such that it can be applied in the disposed space having smaller volume to have the operation characteristic of large capacity requirement. Thus, the passive device manufactured by using the invented method can be applied on the passive device of the present high-capacity miniaturizing development trend and has industrial utilization characteristic and practical application value.
